babel-plugin-minify-mangle-names doesn't rename calls in JSX expressions after mangling the variable name

**Describe the bug**

When I try to transform a code using this plugin, it mangles the name correctly and replaces all the mangled variable calls with the new naming except for JSX expressions.

**To Reproduce**

Minimal code to reproduce the bug

```
Import Flex from 'some-library';

const Component = () => Something
```

**Actual Output**

If there is no Error thrown,

```
Import i from 'some-library';

const s = () => Something
```

**Expected Output**

```
Import I from 'some-library';

const j = () => Something
```
